Umarex Dual 12g CO2 Quick-Connect Adapter

The Umarex CO2 Adapter offers a convenient solution for airgun enthusiasts looking to replace bulky 88-gram CO2 cartridges with two compact 12-gram options. Designed for compatibility with popular models like the Umarex AirJavelin, Umarex 850 M2, and Hammerli 850 AirMagnum, this adapter simplifies reloading by allowing shooters to use widely available 12-gram cartridges instead of hard-to-find 88-gram tanks. Perfect for casual shooters or those who prefer shorter sessions, this accessory eliminates waste by letting users fire just a few shots without discarding leftover CO2 from larger cartridges.

Crafted entirely from durable metal, the adapter maintains the same thread pattern as standard U.S.-spec 88-gram cartridges, ensuring seamless integration with compatible airguns. Its straightforward design requires no tools for installation, making it easy to switch between cartridge sizes on the go. Ideal for hunters or target shooters seeking flexibility in ammunition storage and cost efficiency, this adapter helps reduce reliance on bulkier CO2 tanks while maintaining performance.

By replacing one 88-gram cartridge with two lightweight 12-gram options, users enjoy greater convenience when shopping for supplies—commonly found at hardware stores versus specialty retailers. Whether practicing at the range or in the field, this adapter provides a practical upgrade for airguns designed for 88-gram CO2 systems, offering both accessibility and sustainability for every shooting scenario.
